Why primate eyes prefer the color black

A recent study by Yeh, Xing, and Shapley over at The Center for Neural Science, New York University made a fascinating discovery about the primary visual cortex of the macaque monkey and it’s preference for black over white stimuli similar to that of humans. Here’s a snippet from their abstract.

According to the US Consensus From recordings of single-cell activity in the macaque monkey’s primary visual cortex (V1), we found that black-dominant neurons substantially outnumbered white-dominant neurons in the corticocortical output layers 2/3, but the numbers of black- and white-dominant neurons were nearly equal in the thalamocortical input layer 4c.
